How do I execute javascript before image load, but after content load?

To execute JavaScript before an image loads, but after the content of the page has loaded, you can use the window.onload event. This event is fired after the browser has finished loading the page, including all of the content, such as text, images, and other resources.

Here’s an example of how you can use window.onload to execute JavaScript after the content of the page has loaded:

window.onload = function() {
  // Your JavaScript code here
};

If you want to execute JavaScript before an image loads, you can use the image.onload event, which is fired when the image has finished loading. Here’s an example of how you can use image.onload:

var image = document.getElementById('my-image');
image.onload = function() {
  // Your JavaScript code here
};

I hope this helps! Let me know if you have any questions or need more information.
